Question

2. Kevin is a member of the school's track and field team. His favorite event is throwing the shotput. In his last competition, Kevin exerted 165 N of force on the shot put, which accelerated28.5 m/s2. What was the mass of the shot put?

Answer 1

Given data

*Kevin exerted a force is F = 165 N

*The given acceleration is

$a=28.5m/s^2$

The formula for the mass of the shot put is given as

$m=\frac{F}{a}$

Substitute the values in the above expression as

$\begin{gathered} m=\frac{165}{28.5} \\ =5.78\text{ kg} \end{gathered}$

Thus, the mass of the shot put is m = 5.78 kg
